the dispensing conveying line 1 is provided with a hovering mechanism for enabling the containers to stay and then bearing the blanking of the dispensing cabinet; a plurality of transfer mechanisms 9 are arranged on the inflow conveying line 4 at intervals along the conveying direction and are respectively connected with one end of each dispensing conveying line 1; the upstream inlet of the inflow conveyor line 4 is used for loading empty containers, and the downstream outlet of the inflow conveyor line 4 is connected to the inlet of the outflow conveyor line 5;

a plurality of transfer mechanisms 9 are arranged on the intermediate conveying line 3 at intervals along the conveying direction and are respectively connected with the other end of each dispensing conveying line 1;

the control system is used for establishing association between the container information, the prescription information and the position information of the medicament stored in the dispensing cabinet, controlling the hovering mechanism to enable the container to stay or follow the conveying line, and controlling the direction of the transferring mechanism 9 to enable the container to enter and exit the corresponding conveying line according to a preset path.

As an implementation mode, the automatic dispensing system of the above embodiment can be arranged in four rows as shown in FIG. 1, and is used for storing various types of common herbal pieces. Empty medicine barrels 10 are input from the inflow conveying line 4, the control system contrasts with the storage position information of the decoction pieces in the dispensing cabinet according to the matched prescription information, the path of the medicine barrels 10 is planned, the medicine barrels 10 are automatically conveyed to the corresponding dispensing conveying line 1 according to the preset path by controlling the direction of the transfer mechanism 9, the medicine barrels stay under the corresponding dispensing cabinet and continue to move after receiving the medicine, normally, all the types of the decoction pieces corresponding to the prescription cannot be provided by one dispensing conveying line 1, therefore, the medicine barrels 10 are conveyed to the other dispensing conveying line 1 through the middle conveying line 3, and after the medicine receiving of all the types of the decoction pieces in the prescription is completed, the medicine barrels 10 are finally output from the outflow conveying line 5. The types and the positions of the decoction pieces in the dispensing cabinet are reasonably arranged according to the characteristics of common prescriptions, so that the conveying path of the medicine barrel 10 between the transmission lines is shortest.
